Answer: KEYBOARD PLAYER

This puzzle involves playing through a rogue-like game in the browser. Your character is represented by an “@” symbol and the only controls are the 4 arrow keys (no diagonal movement). The goal on each level is to make it to the down staircase (represented by a “>”).

There are 22 levels. After solving a level you are taken to a new unique URL for the next level. These URLs can be shared with teammates so that they can immediately jump to the same point of progress.

Along the way you will encounter several different monsters and obstacles.

@
You, the player, can move in cardinal directions, monsters move after the player moves (and only if the player moves)

C

H

D

E
Elemental, Monster, moves at twice the speed of the player, moves using the shortest path towards the player (smart)
W
Watcher, Monster, does not move, if it sees the player (horizontally or vertically) then it changes to behave like an H
M
Mummy, Monster, moves at the same speed as the player, moves on a path, if it sees the player in front of it then it changes to behave like an H
Z

O

Boulder, pushable by player
(
Key, colored based on which group it belongs to, can be picked up by a player and will then open a door of the same group
~
Switch, colored based on which group it belongs to, can be triggered by monsters, player, or boulders, when all switches of a group are triggered at the same time, it will open a door of the same group
+
Door, colored based on which group it belongs to, opened when all switches of the same group are triggered at the same time, or when a player holding a key of the appropriate group touches it
/
Portal, colored based on which group it belongs to, when any object moves onto the same square as a portal it is teleported to another portal of the same group and then moved one more square forward in the same direction

At roughly the halfway point through the levels, a new mechanic is introduced where there is a second character “@”. The movement keys move both @ characters at the same time. The goal is to keep both @ characters alive and take them both to the 2 down staircases (they must both be on the staircases at the same time).

Here are the direct URLs for each level:

In the final level there is no down staircase. Instead there is an " symbol which represents the amulet, and a collection of monsters represented by lower case letters. After making your way to the amulet the monster letters will spell out the final answer, KEYBOARD PLAYER.
